Hi,
I did my BA assesment on the 26 Feb, but unfortunately they wrote to me and said they will not be taking my application further this time!!! Bastards! Although I haven't asked them for feedback on where I failed yet.
To answer you questions, I read that the pass mark for the numerical test is 15/25 or 15/30 (sorry couldn't remember how many questions there were!) And you would be pleased to know we didn't have to do any group assesments, they were all individual tests.
So best of luck,
BTW
